[QUOTE="sawtooth, post: 54675"] Did you do the firmware update? I tried to put it on a friend's slot loader and it totally horked the system. I ran the installer and it told me I needed the firmware update. So I canceled out of it. Turns out that this will mess up your iMac for some reason. If I booted it up it would start but no display. But if I put it to sleep and woke it up it would work fine. But then it got really funky and I had to put a VGA monitor into the plug in the back (under the cover). It took many hours of work, but eventually I got it to where I could run the firmware update and then install panther. There are websites that tell you all about it so I guess it is a pretty common problem. The documentation with the installer says nothing. Just that if you need update in firmware it will tell you.
